Players are players – once they’re at All Slots, they can have fun on any of the promotions available (many of which are available at all the Jackpot Factory casinos anyway).
As far as Welcome Bonus…. a player can receive only one Jackpot Factory Welcome Bonus – no matter whether he’s playing at AS on a WJ account number or if he signs up for a new AS account number.
Hope this helps,
